Robot Oousu ロボット・大碓

A bizarre transformation originally envisioned for Ousu's older twin brother, Oousu. After their mother's untimely passing, the two brothers would wind up fighting to the death, with Oousu suddenly becoming an ancient karakuri robot while dueling his younger twin brother. Not many details regarding this form are known, though it would end up going unused as the script for Yamato Takeru (1994) underwent revisions.
